Challenge
How do we get access to our legacy and make the most
of it
HART installed base >30 million
What does bring us now and for the future
Process values
Status
Quality
Can we use existing infrastructures
Quality
Commonly used
PB DP >38 million
PB PA >6 million

Uniformity by NE43
First attempt to put information into the current signal, hence given some idea on the status of the measurement Warning
Even brief dips/overshoots in the standardized current signal could be wrongly interpreted as a failure signal. The failure should be present for at least 4 seconds or a minimum of 2 signal scanning cycles.

Monitor your infrastructure
Awareness of applicability
How can you get access
NOT just values
BUT Health, Quality values
How do you disclose this

Do we meet our challenge?
What relevant information is available from a HART or PROFIBUS device?
What is relevant depends on the application Operator : Process values and (condensed) Status
Training, education
Maintenance : Detailed (consistent) diagnostics and events
Training, education
20
Do we meet our challenge?
What can we use to implement HART instruments with Profibus?
Remote IO
Support of HART transparent channels. Availability of certified Communication DTM or Device Driver If required meeting HART 6 specifications (e.g. 32 characters tag, device status for every HART values [PV, SV, TV, QV].
PROFIBUS DP/PA Coupler
Hook up some 4 HART instruments to DP or PA
21
Do we meet our challenge?
Can we use the existing infrastructure
Very likely, there are instruments to help you find out
Usually setting up a worst case would give you enough information (e. g. the longest run) There modules to help you improve your impedance
22
Do we meet our challenge?
How to monitor the health status of your HART and PROFIBUS devices?
For the control system it will probably to costly to implement for each instrument the diagnostics available By applying an Intelligent PROFIBUS Access Point in parallel (bypass) to Process Automation System which is able to monitor Health Status of connected HART (pass‐through) and PROFIBUS devices according to NAMUR NE107
